Hereinafter, the operation and effects of the contaminant conveying device using the air pressure according to an embodiment of the present invention.

The impurities are introduced into the hopper 120 through the flight conveyor, and the impurities are introduced into the hopper 120 and introduced into the device main body 110.

At this time, since the swing valve 132 provided at the inlet 112 of the device body 110 by the operation of the driving unit 135 is in a state in which the inlet 112 is opened, the contaminant introduced through the hopper 120 is a device. It is stored in the collection chute 115 provided inside the main body 110.

In addition, the contaminant remaining in the hopper 120 when the contaminant is introduced is pumped into the device main body 110 by the air pressure injected through the injection nozzle 185 of the injection pipe 184.

Due to the air pressure of the injection pipe 184, the remaining contaminants of the hopper 120 can be pumped to solve the problem that the contaminants are caught between the inlet 112 and the swing valve 132.

Then, when the contaminants are filled in the collection chute 115, the swing valve 132 is rotated by the operation of the drive unit 135 to block the inlet 112 and to seal the inside.

The inner edge of the inlet 112 is provided with a gate seal (not shown) in contact with the swing valve 132 to improve the sealing force inside the device body (110).

When the inside of the device body 110 is sealed in this way, the compressed air is injected through the compressed air inlet pipe 146 from the air pressure supply unit 140 into the device body 110.

Is not stagnant and is easily moved through the transfer pipe 150.

The convoluted material moved through the conveying pipe 150 passes through the curved portion of the conveying pipe 150. The inner surface of the curved portion of the conveying pipe 150 is provided with a spiral rib 155 to provide sand and the sand included in the contaminated material. It can prevent damage by the same foreign matter and can provide a smooth flow.

Then, the miscellaneous material moved through the transfer pipe 150 is transferred to the storage chamber via the air chamber 160.

The air chamber 160 is formed with an air pressure outlet pipe 162 to perform a decompression function because the air pressure of the transfer pipe 150 flows out, and the miscellaneous material along the guide rib 164 formed on the inner surface of the air chamber 160. It may be transferred to the storage compartment 170.

In addition, since the transfer pipe 150 is connected in the tangential direction of the air chamber 160, the contaminants discharged from the transfer pipe 150 may be discharged along the inner circumferential surface of the air chamber 160 to reduce noise, impact, and wear.

According to the present invention as described above, when the input of the contaminant can be prevented from remaining of the contaminant in the hopper, the malfunction is tightly sealed inside the main body of the device and the performance is improved, and the transfer performance can be improved by improving the conveying piping. have.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand.
